My mini CPAP has been around the world several times, use on planes, & its versatile power supply meant it cold be used anywhere, regardless of voltage, frequency, etc. I bought it for travel convenience, but nit has been so much more. It is disappointing to find that the filter is no longer available. That's all I need, so if there is one or more anywhere, please contact me.

Just what I was looking for-pleasant knowable service-good price-fast delivery!

This order was placed on Friday and received on Monday... I couldn't believe it! What speedy service! Thanks ever so much!
